Mitsubishi Electric begins mass-producing first crankshaft-mounted ISG system for 48V hybrids; used in Mercedes-Benz vehicles

Mitsubishi Electric Corporation has begun mass-producing the auto industry’s first crankshaft-mounted integrated starter-generator (ISG) system for 48V hybrid vehicles, which will be mounted in Mercedes-Benz vehicles. The system will be on display during 45th Tokyo Motor Show 2017.

Belt-driven system ISG systems use a belt to transfer power from the motor to the engine; this, said Mitsubishi, can limit both maximum torque with abrupt force transmission and the motor’s peak power output. By contrast, connecting the motor directly to the engine crankshaft eliminates the limitations of the belt system and enhances both motor output power and power generation.

Mercedes-Benz 48V system debuts in new S-Class

July 19, 2017

Mercedes-Benz’ new S-Class will enter the market this month with an all-new engine range (diesel and gasoline variants of 6-cylinder in-line engines and a new V8 biturbo gasoline engine) with a series of new technologies for electrification of the powertrain (earlier post), including a 48V system (S 450 and S 500 models) and Integrated Starter Generator (ISG) for mild hybrid functionality, an electric booster compressor, and an upgraded plug-in hybrid model.

The 48 volt system establishes a third on-board power network. It fills the gap between the 12 volt network already established for decades and the high-voltage network required by electric vehicles. The latter makes special safety precautions necessary, can therefore only be used to good effect for a small number of components and is limited to driving functions. As the power requirement increases, the limited voltage of the conventional 12 volt network leads to a constant increase in current levels, and therefore to supply lines with large cross-sections. It is however not being replaced, but rather supplemented by the 48 volt network.

A123: Increasing 48V battery power up to ~25 kW enables advanced mild hybrid capabilities with greater fuel savings

April 06, 2017

In a paper presented at SAE WCX 2017 this week in Detroit, engineers at Li-ion battery maker A123 Systems conclude that 48V battery packs with strong power (up to ~25 kW) and HEV-level energy capabilities (<200Wh for most scenarios) are needed to enable advanced mild hybird (MHEV) capabilities, with optimal power-to-energy ratios between 30 and 160.

Improving battery power to such as level would further enable hybridization to near-HEV levels as well as engine downsizing, thereby enabling fuel economy improvements beyond the current 10-15% MHEV limit. Additionally, new electrified features could be added, such as electric turbo/supercharging, electric traction, electric power steering, electric suspension and electric air conditioning. To address these needs, the A123 team presented a high-power, lithium-iron-phosphate chemistry with excellent rate capabilities.

ICCT: incremental technology can cut vehicle CO2 by half and increase fuel economy >60% through 2030 with ~5% increase in price

March 22, 2017

With the EPA re-opening its Mid-Term Review of GHG standards for 2022-2025 for light-duty vehicles (earlier post), and with NHTSA yet to weigh in on its Mid-Term evaluation of fuel economy standards for the same period, a team from the International Council on Clean Transportation (ICCT) has published a report analyzing emerging vehicle efficiency technologies; their ability to achieve lower emission levels; and their costs in the 2025–2030 timeframe.

Starting from a baseline 26 mpg (9.04 l/100 km) in 2016, the The ICCT team assessed increased consumer label fuel economy (as opposed to the regulatory test fuel economy) to 35 mpg (6.71 l/100 km) in 2025 and to 42–46 mpg (5.6-5.11 l/100 km) (under three scenarios) by 2030. These fuel economy levels are achieved based on a sustained 4%–6% annual reduction of fuel use per mile with incremental technology additions that do not compromise vehicle size or utility at an incremental cost of $800–$1,300 from 2025 to 2030. The resulting trajectory would reduce CO2 emissions by half and increase fuel economy by more than 60% from 2016 through 2030. Based on a detailed analysis of the efficiency technologies used to achieve these lower CO2 emission levels, the ICCT study concludes that vehicle prices would increase by about 5% by 2030.

Honeywell Transportation Systems Forecast: turbocharged vehicles to account for 48% of annual global sales by 2021; electric boosting emerges

December 09, 2016

Honeywell’s Transportation Systems Forecast projects that turbocharged vehicles will acount for 48% of annual global sales by 2021, up 9 percentage points from 2016. This annual sales estimate, combining both passenger and commercial vehicles, would add more than 232 million turbocharged vehicles globally between 2017 and 2021—an increase of 35% from today.

This year’s forecast recognizes an industry trend for slightly bigger engine sizes in Europe and China as automakers adapt powertrain strategies to tackle updated emissions regulations developed for real-world driving conditions. In these regions, a typical powertrain is a three- or four-cylinder engine with a displacement size between 1.2 liters and 1.7 liters. By rightsizing engines with available technologies, automakers are able to continue applying the benefits of smaller turbocharged engines while fine-tuning powertrain systems to further optimize fuel economy, emissions and performance.

ICCT: 2025 target average of 70 g/km CO2 for new cars in EU feasible and economical; more so with electric drive

A 2025 CO2 target of an average 70 g/km for new cars in the EU could be met with very little electrification and with an average payback period of less than 4 years, according to a new study by the International Council on Clean Transportation (ICCT). However, transitioning soon to electric drive could lower manufacturers’ compliance costs by as much as €500 (US$532) per vehicle in 2025.

Under current European Union regulations, average new car CO2 emissions must decrease from the present 120 grams per kilometer (g/km) to 95 g/km by 2021. Although no further reductions are presently mandated, new targets for 2025 and 2030 are under discussion in Brussels. In 2013 the European Parliament recommended an “indicative range” of 68–78 g/km for 2025, while holding out the possibility that even lower targets should be considered if justified.
